Ammonia, however, is not without hazards. <> <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Corrosion can also be enhanced in industrial ammonia refrigeration systems that have heat-transferring liquids such as calcium chloride or sodium chloride. Clean ammonia unit when needed and contact a water treatment company if water contamination is detected. %PDF-1.5 Should parts of the system such as pipes, joints or valves need to be removed, a properly qualified person will need to ensure the relevant parts of the cooling systems have been depressurized and purged of Ammonia. Additionally, in systems designed to be oil-free, internal corrosion may occur. Industrial Ammonia Refrigeration systems have components such as compressors, piping and vessels which are designed to contain ammonia at the correct pressure. DRAFT Final Dec. 6, 2019 6 . Applus+ offers a wide array of inspection methods to guarantee the integrity of equipment and safety of ammonia cooling systems Potential areas of concern within the ammonia refrigeration industry include internal and external corrosion , pitting and wall loss, touch point corrosion at pipe supports, damage and deterioration to protective coating and insulation, and damage to pressure safety and relief valves. endobj 11 0 obj )N���6`�� ��yt�W�'�޺��c���XȔ���k��w�?��a'�-5T��V�@�2�����f��O1|��9O�a��s���|��H!X�G)e��X�T �Y’~�{�⭈K�̡��~�P 9 0 obj Ammonia Refrigeration Safety Inspection Checklist October 31, 2019 Issued in 1992, the Occupational Safety and Health Administration’s (OSHA) Process Safety Management (PSM) regulation is designed to give guidance to facilities regarding the … Chemical treatments for this are available and the advice of suppliers should be rigorously respected. How to Reduce the Risk of Asbestos Exposure in the Workplace, Ammonia Refrigeration Guidelines for Scheduled Inspections, Ammonia Industrial Refrigeration System Start-Up Procedures, Common Hazards of Industrial Ammonia Refrigeration. Ammonia Refrigeration Process Safety – Online Click Here To Register Today. Ammonia dissolves readily in water, forms a strong alkaline solution and gives off heat. This guidance may go further than the minimum needed to comply with the law. This Safety Order is being issued to prevent, avoid or reduce the risk of personal injury or damage to property as a result of an accidental leak from an ammonia refrigeration system. 6 0 obj <> A tragic example of this took place in British Columbia in 2017, when a pinhole in an ice rink brine chiller allowed Ammonia and brine to mix. <> It boils at an atmospheric pressure of -33o Celsius. Ammonia breaks down in the environment very quickly (lasting less than a week in the air). Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air. Ammonia refrigeration companies like Industrial Refrigerated Systems Ltd. provide, for various cooling applications and systems. Care must be taken to reduce corrosion, especially in wet and damp conditions and when metal temperatures are below the dew point.
